集对分析是一种用联系度处理不确定性问题的系统分析方法。提出将模糊联系度的思想应用到差异度系数的取值中,充分挖掘所研究系统中的有效信息,使得对系统的评价和决策更加准确和合理。将此改进的集对分析方法应用于黄土路堑边坡稳定性评价中,并与其他方法进行对比,表明该方法简便、有效。 Set pair analysis is a systematic approach to deal with the problem of uncertainty with the degree of association. It is put forward that the idea of ​​fuzzy connection degree should be applied to the value of coefficient of difference, and the effective information in the system should be fully tapped to make the evaluation and decision of the system more accurate and reasonable. The improved set pair analysis method is applied to the stability evaluation of loess cut slopes, and compared with other methods, which shows that the method is simple and effective.
